Due to this situation enormous conse- quences result for the whole refrigeration and air conditioning trade. BITZER there- fore committed itself to taking a leading role in the research and development of environmentally benign system designs.

The following report deals with possibilities for a short and medium term change to environmentally benign refrigerants in medium and large commercial refrigeration and A/C plants. At the same time, the experience which already exists is also dealt with and the resulting consequences for plant technology.
